1 D ESCRIPTION OVERVIEW OF THE UNITS Eclipse Series multi-function meters are designed to display various types of power measurement information. Eclipse meters are fitted with one factory programmable relay, volt-free normally open contacts. All the connections are captive screw terminals at the back of the meter. The Eclipse 2 front panel has a single line, 16 character display and a set of readout selection buttons. The Eclipse 7 has a 20 character, 4 line display and a set of readout selection buttons. Standard meters are factory programmed and provide a small range of functions which are programmable by the user. They are also supplied with CT Ratio Setting and CT Polarity Check available for user programming. PULSE OUTPUTS One voltage free output is factory fitted in the meter. The relay in Eclipse 2 is set to indicate kwh only. The Eclipse 7 can be programmed to indicate kwh, kvarh* or kvah* on request. The standard setting for the Eclipse 7 is kwh. Pulse value and duration are factory set at 1kWh per pulse 100ms duration. Function 60 enables the user to alter the value to suit individual requirements. The pulse status cycle (code 53) provides a visual indication for testing the meter from the front panel. *Eclipse 7 meters only Fully complies to European Electromagnetic Compatibility Conforms to IEC 1036 Section 4.6.1. Accuracy Class 1.0 Certificate No. 0275 2

INSTALLATION ECLIPSE 2/7 INSTALLATION OF THE METER Eclipse meters should be mounted so that the front panel is vertical. A typical panel would be a switchgear cabinet door. The meter requires a depth behind the panel of 100mm. A single square aperture 92mm wide x 92mm high should be prepared. LOCATION Meters should be mounted in a dry, dirt free environment, away from heat sources and very high electric fields. Temperatures should not exceed 70 o C or fall below -20 o C. POWER SUPPLY Standard 3 phase 4 wire Eclipse meters are powered by 230 volts AC (50 Hz) at 0.2 amps. The units can be powered from a dedicated fused feed, or they may be powered by the voltage source which they are monitoring provided that it is a 230 volt system. A removable protection fuse for the electronic power supply is fitted in the rear of the meter. ELECTRICAL CONNECTIONS 2.5 sq.mm wire is recommended for all electrical connections, subject to the distance between the meter and the current transformer. Phasing and polarity of the AC current and voltage inputs, and their relationship is critical to the correct operation of the unit. WIRING Electrical connections are made directly to the back of the meter. See diagram opposite. 92mm 3 100mm

4 T RANSFORMER S ELECTION CURRENT TRANSFORMER SELECTION For accurate monitoring, correct selection of CTs is critical. The following paragraphs provide the information required to choose the correct CT. CT SELECTION Eclipse Series Meters use current transformers (CTs) to sense the current in each phase of the power feed. The selection of the CTs is important because it directly affects accuracy. The CT secondary rating depends on the current input option installed. The current input rating is 5 amps for the standard Eclipse Series meters The CT primary rating is normally selected to be equal to the current rating of the power feed protection device. However, if the peak anticipated load is much less than the rated system capacity, improved accuracy and resolution can be obtained by selecting a lower rated CT. In this case the CT should be the maximum expected peak current + 25%, rounded up to the nearest standard CT size. Other factors may affect CT accuracy. The length of the CT cabling should be minimised because long cabling will contribute to inaccuracies. Also, the CT burden rating must exceed the combined burden of the Eclipse Series meter, plus cabling, together with any other connected devices. Overall accuracy is dependent on the combined accuracies of the Eclipse Series meter and the CTs. 15

5.3 F IELD S ERVICE C ONSIDERATIONS In the unlikely event that a unit should fail, it will normally be serviced by exchanging the faulty unit with a replacement unit. The initial installation should be done in such a way which makes the replacement procedure as convenient as possible. 1. A Current Transformer shorting block should be provided so that the meter current inputs can be disconnected without open circuiting the CTs. The shorting block should be wired so that protective relays are not affected. 2. All wiring should be routed to allow easy removal of the connections to the terminals. 5.4 P ERFORMANCE C HARACTERISTICS CURVE WITH BALANCED LOAD AT 50 HZ Load curve with balanced load 1 0.8 PF 0.5 lag 0.6 PF 0.8 lead 0.4 PF 1.0 % Error 0.2 0 1 4-0.2-0.4-0.6 0.25 0.5 1.5 2 2.5 3 3.5 4.5 5-0.8-1 Amps 17 The attention of the specifier, purchaser, installer and/or user is drawn to special measures and limitations or use which must be observed when these products are taken into service to maintain compliance with the CE Directives.
